Physics · Secondary 4 · Hard · Resultant force and F = ma
Two blocks, P and Q, are on a horizontal surface. P has mass 3.0 kg and Q has mass 2.0 kg. A horizontal force of 25 N pulls both blocks so that they accelerate together at 4.0 m/s².
What is the frictional force acting on the blocks from the surface?
